IMPROVEMENT IN RUBRER SPRINGS PoR Usn INsHIPs, cARs, AND PoR OTHER PUR-v Poses.

To all whom it may, concern: e

Be it known that L'J AMES A. J oYNER, of the city, county, and State ofNew York, have invented a new and useful Improvement in Rubber-Springsto-be applied for relieving sudden jerks or, strains in the chains orropes used in ships for steering, in draught-chains,

and in similar positions Where a spring is required,

` which will yield a certain distance without impairing the fullstrength of tl1e cable, chain, connection in which it may be inserted.

Inthe annexed` drawings- .Figurel is a perspective' view of'a springmade ac-' rope, or other cordiug tomy invention;

Figure 2 is a longitudinal section of the same; and

Figure 3 shows the mode of applying such spring in relieving the jerkorstrain on the cables, ropes, or tackle 4used in working a ships rudderor lstanding rigging. Y

The 'folloyving explanation will `enable any one to make and use myinvention.

. The size of the spring will be, in each case,mo1ifiedv to suit theapplication to whichI it is to be made.

Thel sectional view in fig. 2 shows all the part-s of a spring madeaccordingto my invention. v d The loops 0r' rings A A serve to connectthe spring' with a chain, as in iig. 3.

The rods b 1)' pass' through the vulcanized rubber springs B B', andhave nuts or heads, c c, holding caps,

E E', against the ends of the rubber springs.

The springs B B are inserted in the head-pieces D` `D', which arefastened by male and female screws to i the barrel or case F, whichencloses and connects the `whole. i '1 The Schedule referred to in theseLetters- Patent and making part of theame This case must 'be made largerin diameter than the rubber springs B B', so as to leave a space betweenthe springs and the case, in order to Apermit the conipression of thesprings by tension on the loops A A" and rod b b.

I have described the barrel F as containing two springs, B B', but avery good spring may be made by using only one piece of rubber, B, withrnd b of sui- In' this case, the other cient length to ll the barrel. l

loop is attached to the opposite cap D.

n By the construction of my spring, it serves at the same time as aspring and as a swivel.

For the loops A A may be substituted hooks, or

other-connecting devices.

IMy invention is found of great value on the chains,

cables, stays, rigging, and the like, used in ships.

Also, in Adraught-chains, links, and the like, in lailroad and othercarsand vehicles.

Having thus described my invention, Wh'at I claim, and desire to secureby/Letters Pat ent of the United States, is-

1. The improved spring, herein described, composed of the parts A, B, b,c, D, E, and F, or their equivalents,combined and arranged,substantially as described.

2. The combination of the spring, herein described, `with a chaincable,or the like,in the manner and for the purpose set forth. j
